ALBERT (fALETON (Iltl'ltltll lELU, Old KUSALIA, WASHlNtlTObh FEPJEGIFIGATION forming part of Letters Patent 1V0. 783,821, dated February 28, 1905.

Application filed May 10, 1904. Serial No. 207,275.

To a, IIJ/I/O'III/ it mm/y concern.-

Be it known that I, ALnnn'r (Murrow Unrren'mnm), a citizen of the United States, and a resident of Rosalia, in the county of VVhitman and State of l/vashington, have invei'lteda new and Improved Feed-Regulatm' for 'ihreshirig-Machines, of which the following is a full, clear, and exact description.

My invention relates to a feed-regulator for threshing-machines; and its n'incipal object is to provide means for preventing too large a quantity of material being fed into the machine irrespective of the amount placed upon the feeding device itself.

My invention is applicable to all kinds of threshinganachines and to other machines of a similar character, and 1 do not wish to be limited in that respect.

Reference is to be had to the accompanying drawings, forming a part of this spccilicatioi'i, in which similarcharacters of reference indicate corresponding parts in all the figures,

l igure .1. is a perspective view showing a feeding device for a threshing-machinc with a preferred form of my improvement applied thereto. Fig. 2 is a sectional view of the same on the line 2 E2 of Fig. 3; and Fig. 3 is a sectional view on the line 3 3 of Fig. 2, showu'ig the regulating device in elevation.

ln the drawings, 11 re nesents the frame of a feeding device for a threshing or similar machine. This frame may be of any d esi red. constructi on and may be provided with a conveyor of any desired character, this conveyor being rc presci'lted in the drawings by the numeral l2.

13 is a shaft for operating the conveyer, and my invention contemplates the connection of this shaft or some other moving part of the conveyor with the regulating device, which is to be applied to the conveyor. As a convenlent means of accomplishing this I. have shown a sprocket-wheel 14 on the shaft l3 and a chain 15 in engagement therewith and passing under idlers 16 into engagement with a sprockctavheel 17, connected to the regulati ng device. I

18 is a bar adjustably attached to the franiework 11 by means of a slot 19 and a bolt 20. This bar receives a shaft 21, upon which the sprocket wheel 17 is secured. A pair of l sprocket-wheels 22 arealsoseeured to the shaft sprocket-chains 23, which also pass over the sprocket'wheels 24- upon a shaft Secured to the chain 23 are a series of slats other and extending across the regulator from one chain to the other. Projecting outwardly from each of these slats is a series of pointed pins or spikes 27.

Although l have described my regulating sprocket-chains, and slats, it will be obvious that .1 may substitute other equivalent ele' ments for these without departing from the spirit of my invention, and that the essential points are to secure a series of traveling pointed pins in proximity to theconveyer '12.

28 is a bar to which the framework 28 of the regulator is secured, and which is supported by uprights 2.) and can be adjusted to any desired height by means of a series of holes 30 in each of these uprights. The framework 28 comprises longitudinally-disposed bars 28", which carry the afm'esaid shafts 2i and. 25, and these side bars are cormected by cross-bars 28, disposed near the extrmnities of the framework, as indicated.

lt will be obvious when the eoi'iveyer travels in the direction shown by the arrow adjacent to it in Fig. 2 that motion will be communicated, by means of the connectimls shown, to operate the endless chains of the regulator in the opposite direction, as shown by the other arrow in Fig. 2. The pointed pins upon the regulator will serve to catch and prevent onward motion of the material carried by the conveyor 12, provided such material is in ex cess of a certain amount. This amount can be determined by meansof adjusting the reg ulator as to height in the holes 30 and as to angle in the slot 19, it shouldnow be understood that the chains 2?), in connection with the slats Q6, constitute an endless belt.

It will be obvious that my regulator may be easily attached to a machine of any construction after the machine is built, that it is very simple in operation and inexpensive, that it cannot fail to work when properly adjusted, and that it is adjustable by means of the arm 21 and are provided with a pair of emlless 26, preferably in parallel relation with each device as (JOIDIHlSlHg' the sprocket-wheels,

18 while in operation. In this manner the amount of material fed to the machine may be regulated without stopping any of the parts, which is a point of great importance.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A feed-regulator comprising in combination, a main conveyer-belt a sprocket-wheel moving therewith, uprights at the sides of said co'nveyer-belt and having a plurality of alining openings therethrough,a transverse bar removably mounted in said openings, a framework carried upon said bar, an endless belt carried upon said framework and having outwardly-projecting spikes, a sprocket-wheel carried by'said framework and adapted to drive said last belt, a chain passing over said sprocket-wheels, tightening-pulleys cooperating with said chains, a bar attached to said framework and having a slot therethrough, and a bolt passing through said slot and attaching said bar to one of said uprights.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
